How to Archive PSA Data in SAP NetWeaver Business Intelligence (NW7.0)
Data volumes in the entry layer (Persistent Staging Area - PSA) of the SAP BI systems very often heavily increase over time. However, since the data might be needed for further requirements and often can not be re-loaded from the original source systems, it can not be deleted from the SAP BI system for good. A solution might be to create an additional layer in the SAP BI system based on DataStore Objects which can be archived using the standard BI Archiving functionality, or to use a product from a 3rd party vendor. Alternatively, this How-to guide provides a solution to archive data from PSA based on ADK (Archiving Development Kit).
